You are really being stubborn.
Look at the numbers in the thing I quoted from the Paris Energy group or whatever it was. Or look up the numbers yourself; about 20% of the electricity supply in North America comes from nuclear, about 20% from hydro, wind, solar, and the rest from fossil fuels, oil, coal, gas.
To substitute nuclear for the fossil fuel means that three times as many new nuclear installations have to be built as already exist. Found out how many already exist and multiply by three then tell me how they are going to be built, by whom and out of what, and over how long.
And that only subsitutes for fossil fuel used for electricity generation, now you have to more or less double the electricity generating capacity to have enough electrical energy to charge up your air cars or battery cars. This means you need to build something like ten times as many new nuclear plants as already exist.
It is not going to happen.
